Iguanodonts are a group of ornithopods that are larger than hypsilophodonts are, and are also related to the hadrosauriformes. They have been found on almost all continents.

They originated in the middle Jurassic period and survived into the late Cretaceous.

Iguanodontians were one of the first groups of dinosaurs to be found (i.e. Iguanodon itself). They are among the best known of the dinosaurs, and were among the most diverse and widespread herbivorous dinosaur groups of the Cretaceous period. Derived iguanodontians were generally large animals, and Iguanodon was the largest at 33 feet (10 meters) in length with a weight of about 4 tons.
